PITTSBURGH - The Toronto Blue Jays have placed right-handed reliever Zach Pop on the 15-day injured list with a right hamstring strain.
Pop sustained the injury in the eighth inning of Toronto's 11-5 loss at Boston on Thursday and had to be helped off the field.
He pitched two-thirds of the eighth before exiting, giving up two hits and three earned runs.
Pop, from Brampton, Ont., has a 4.85 earned-run average over 13 innings for the Blue Jays this season.
The Blue Jays recalled Jay Jackson from triple-A Buffalo on Friday to fill in for Pop and activated him before their series-opening game against the Pittsburgh Pirates.
